Okay,finally got a chance to try it out.
No issues on an 0411,a V6 pcm didn't unlock but did read cal/OS info iirc.
I did want to post up that this will not work using an AVT-838 though.
I got my AVT boxes mixed up,really wanted to keep my old serial box hooked up to my shop computer/bench harness.
But the old box wouldn't reset/initialize using this tool.
The new USB 85x box hooked right up and no issues though.

I still have a couple pcm's to run through,and i'll post up the info from them as well as the V6 pcm that didn't work.
(it's one of the bastard 98's)
